CVE-2024-6508

8.0 HIGH

📋 TL;DR

This CVE describes an OAuth2 CSRF vulnerability in the OpenShift Console where insufficient entropy in state parameters allows attackers to log into a victim's application account using a third-party account. It affects OpenShift deployments using OAuth2 authorization code or implicit grant flows. The vulnerability enables account takeover without victim interaction.

💻 Affected Systems

Products:
  • Red Hat OpenShift Container Platform
Versions: Multiple versions as specified in Red Hat advisories
Operating Systems: Linux
Default Config Vulnerable: ⚠️ Yes
Notes: Affects OpenShift Console deployments using OAuth2 with authorization code or implicit grant types. The vulnerability is in the state parameter handling during OAuth flows.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete account takeover of OpenShift Console users, allowing attackers to access sensitive cluster resources, deploy malicious workloads, exfiltrate data, and potentially pivot to underlying infrastructure.

🟠

Likely Case

Unauthorized access to victim's OpenShift Console session, enabling privilege escalation, configuration changes, and access to applications running on the cluster.

🟢

If Mitigated

Limited impact with proper network segmentation, strong authentication controls, and monitoring; attackers would need specific preconditions and network access.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires the attacker to trick a victim into initiating an OAuth flow and intercept/modify the state parameter. The vulnerability is in the OAuth protocol implementation rather than requiring complex code execution.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Multiple versions as per Red Hat advisories (RHSA-2024:10813, RHSA-2024:7922, RHSA-2024:8415, RHSA-2024:8991, RHSA-2024:9620)

Vendor Advisory: https://access.redhat.com/errata/RHSA-2024:10813

Restart Required: Yes

Instructions:

1. Identify your OpenShift version. 2. Apply the appropriate Red Hat security update via 'yum update' or your package manager. 3. Restart OpenShift Console services. 4. Verify the update applied successfully.

🔧 Temporary Workarounds

Disable vulnerable OAuth grant types

linux

Temporarily disable authorization code and implicit grant types in OAuth2 configuration if not required

oc patch OAuth/cluster --type='merge' -p '{"spec":{"identityProviders":[{"type":"...", "mappingMethod":"..."}]}}'

Implement additional CSRF protections

all

Add custom CSRF tokens or implement same-site cookie policies for OAuth flows

🧯 If You Can't Patch

  • Implement network segmentation to restrict access to OpenShift Console
  • Enable multi-factor authentication and monitor for suspicious login attempts

🔍 How to Verify

Check if Vulnerable:

Check OpenShift version against affected versions in Red Hat advisories: oc version

Check Version:

oc version

Verify Fix Applied:

Verify installed packages match patched versions: rpm -qa | grep openshift-console

📡 Detection & Monitoring

Log Indicators:

  • Multiple OAuth authorization requests with similar state parameters
  • Unusual login patterns from unexpected locations
  • Failed OAuth state validation errors

Network Indicators:

  • Unusual OAuth redirect patterns
  • Multiple authorization requests to /oauth/authorize endpoint

SIEM Query:

source="openshift-console" AND ("state parameter" OR "oauth authorization" OR "CSRF")
